Title: Any NES Geeks out there who know repair? Post by chadwulf on 18. Oct 2013 at 01:35
Hi, I'm both a collector and a re-saler.
Working on my systems is no big deal, from NES consoles to the 3DS. This is not a simple issue, if you have not had experience with these, please move on. I don't need guesses. I've got a number of NES consoles with several issues. The most common of which is the "lines" fuzzing through the screen. (See picture) I am well aware of the NES connector fix, I've performed it on about 40 consoles just this year. That is not the issue. With a new pin, these consoles give me a solid light, but have A) a blank screen, from black to white, depending on the game B)a scrambled screen with coding symbols all over it. C)lines crisscrossed like a wire fence D) lines crossing the screen vertically (see picture attached, sorry I didn't take time to take pictures of the rest) The symptoms are the same with both the RF port and the normal RCA jacks. I'm fairly confident the issue is with the board itself, but I don't see anything fried on it. No sign of corrosion etc, not even worn where the PIN connects. Soldering, de-soldering, and rewriting lines (with a solder pen) on the board is not a problem for me. My guess is that whatever part of the board processes the video is the issue, but has anyone been able to fix this? Has anybody EVER figured this problem out that we know of? repaired game systems= less retro game systems in the landfill and a continued impact on todays generation :p Any help would be appreciated!

I had a similar issue with ugly Sega Genesis scan lines and harsh audio that was solved only after replacing all the capacitors. Looks like some re-caps on some of your consoles are in order. Have you checked the resistance on your capacitors with a multi-meter? The electrolytic is finite and burns out over time, eventually killing the cap causing erratic and unstable electrical currents creating A/V problems. After re-capping you essentially bring the system back to an electrically "like new" state (except for the state of your 72 pin connector and cleanliness/dirtiness of your games) You can buy complete kits here for $3.95. All you need is soldering skills and a bit of patience to restore the motherboard. At the very least it is certainly worth re-capping one of your faulty consoles to see what happens. http://console5.com/store/kits/game-console-cap-kits.html?cat=123&console_type_revision=60
